Green Glove: These Baseball Boys pick up eggs found on the ground or catch them from Yoshi and throw them at him. If hit, Yoshi is pushed back. The Green Glove can be lured to send the egg into a desired target.

Slugger: This type of Baseball Boy directly hits the eggs thrown at them back toward Yoshi, and can also hit objects as large as Chomp Rock Boulders rolling at them back. They will also swing at Yoshi if he gets too close.

Baseball Boys are similar to Chargin' Chucks, who appear in Super Mario World, in some respects. Both groups appear to be athletes of an American sport, and both take three jumps to defeat. Also, Yoshi can't use his tongue against the two groups either.
